String Trimmer Line 0.080 Inch DWO1DT802 Replacement for Dewalt Weed Trimmer Line 200 Feet DWO1DT801 Compatible with Dewalt Weed Eater String 20V 60V DCST920P1 DCST972B DCST920B DCST970B Yellow

What It Is

This is a 0.080-inch diameter replacement string trimmer line, 200 feet total, designed for DEWALT 20V and 60V cordless weed trimmers. It’s a direct fit for models like DCST920P1, DCST972B, DCST920B, and DCST970B, and also works as a compatible refill for the DWO1DT801 spool.

Fitment & Compatibility

Before buying, confirm your trimmer uses 0.080-inch line diameter—this is thicker than standard 0.065-inch line, so it won’t fit trimmers designed for thinner line. It’s specifically made for DEWALT’s 20V/60V line (models listed above) and is not compatible with gas-powered or other-brand trimmers unless they also accept 0.080-inch line. The line is pre-wound on a spool that fits DEWALT’s bump-feed heads, but if you have an older or third-party head, you may need to manually wind it. Check your trimmer’s manual or existing spool for diameter specs before purchasing.

Key Things to Know

• Quality: The line is durable and resists fraying, but it’s slightly stiffer than 0.065-inch line, which can reduce trimming efficiency on light weeds.
• Installation: Easy if you’re replacing a spool—just snap it in. For manual winding, cut to 20-25 feet, feed through the eyelet, and wind evenly to avoid jams.
• Gotcha: This line is yellow for visibility, but color doesn’t affect performance. If your trimmer has a fixed-line head (not bump-feed), you’ll need to cut the line to length yourself.
• Compatibility: Works with DEWALT’s quick-load spool system; no adapter needed for listed models.

Should You Buy It

If you own a DEWALT 20V or 60V cordless trimmer and need a reliable, pre-wound 0.080-inch line for heavier weeds or edging, this is a solid, affordable pick. It’s not for light-duty trimmers or those requiring 0.065-inch line, but for the listed models, it’s a direct upgrade in durability.
